He is saying that in order to statically parse an eval block, you must know when_it_halts - or in otherwords - what it does; this is impossible with out actually running the eval block, and is clearly related to the halting problem.

If he's saying that, then he's wrong. The problem is not the existence of eval; the problem in Perl 5 is barewords and prototypes.
